It is still made by Zilog, and still stocked by Digikey.

Look again, they list it but have zero stock. That however is
certainly a key part if you wnat to do the SCSI as minimal
parts count.
However, watch out as the Nmos part and the Cmos part
are not completely interchangeable due to implementation
oddities. If memory serves the 53C part is also preferred
over the NMOS as less buggy.
If you want to know how to hook it up to a z80 see the
AmproLB+ schematics.
